Altaic etymology :

Comments:EAS 79, 141. Somewhat dubious as a PA etymon: the Turkic reflex is questionable, the Tungus forms may be borrowed from Mong., see TMN 1, 507-508, Doerfer MT 25, Rozycki 159 (although the vocalism is not quite satisfactory for a loan); however, the Kor. word is hard to explain as a Mong. borrowing.
